The math, shown
Full methodology →How it crashes
NHTSA’s own crash tests, separate from the reliability score above.
NHTSA hasn’t published a crash-test rating for this model year. That’s common for lower-volume or older models. It doesn’t mean the car is unsafe, just that this program hasn’t tested it.
